Solution preventing decomposition of samples
WebJul 27, 2024 · Preparation: Fixation - chemical fixatives preserve tissue by preventing degradation, and help to maintain the structure of the cell and of sub-cellular components. The most common fixative for light microscopy is 10% neutral buffered formalin. Dehydration - water is removed from the sample as it does not mix with embedding media. WebFor example, since ascorbic acid is easily oxidized by dissolved oxygen or iron(III) ions in an aqueous solution, its concentration decreases over time. If this occurs, we recommend reducing the pH level or masking the iron ions with EDTA or 2Na and injecting the sample promptly after preparation.
